Fibre Channel link failures
You might need to solve problems on the Storwize® V3500 system and its connection to the storage area network (SAN) when an optional Fibre Channel host interface adapter is being used.When a failure occurs on a single Fibre Channel link, the small form-factor pluggable (SFP) transceiver might need to be replaced.
Before you begin
The following items can indicate that a single Fibre Channel link
failed:
- The SAN monitoring tools of the customer
- The Fibre Channel status LEDs at the rear of the node canister
- An error that indicates a single port failed
Procedure
Attempt each of these actions, in the following order, until the failure is fixed.
- Ensure that the Fibre Channel cable is securely connected at each end.
- Replace the Fibre Channel cable.
- Replace the SFP transceiver for the failing port on the node.
- Perform the Fibre Channel switch service procedures for a failing Fibre Channel link. This procedure might involve replacing the SFP transceiver at the switch.
- Replace the Fibre Channel adapter on the node.
- Replace the Fibre Channel host interface adapter. Refer to Replacing a host interface adapter, ensuring the Fibre Channel Small Form-factor Pluggable (SFP) transceivers from the failed host interface adapter are reused with the replacement host interface adapter.
